Bought the motor brand new in February and in October had the air injectors changed because motor did not want to start right up after long run. Problem was fixed. Well 3 weeks ago motor would run good but then would sound like it would have a mis and run bad, I would idle down it would clear up in 10 seconds and run great. The problem got worse brought it to shop and they had it for 2 weeks and said the air injector was bad again. Got it back and went out this past weekend and motor did not want to idle, it idle rought and up and down with the rpm. Took off and ran good when running, slow down to under 2000 rpm and did the same, rough and up and down rpm. Any ideas? Bought a brand new motor so i wouldnt have to worry about anything and this hunting season has been problems, brand new motor problems. Starting to wish i never sold my old mercury to get new tohatsu. Any comments are welcome, thanks.
